Sensor-bearing for small electric motors

Universal Motors typically use a speed sensor (tachometer) to provide speed feedback to the motion control system.

SKF Sensor-Bearing Units provide the following multi-sensing functions in addition to the normal bearing operation:

  • The relative position of the inner ring in relation to the outer ring
  • The rotational speed
  • The direction of rotation
  • The magnitude of acceleration or deceleration

Permanent Magnet brushless DC motors frequently use hall sensors or encoders to sense the rotor position. SKF also provides specific sensor-bearing solution to sense absolute position of the rotor.
